' This invention relates to a mixing device particularly adapted for use in the intake manifolds of internal combustion engines, and more especially to an apparatus for c throwing the heavier particles of fuel against the walls of the manifold in such manner- '20 manufactured by stamping and which may be accordingly very cheaply manufactured.

These and other objects I attain by the construction shown inthe accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure l is a plan view of a mixing device constructed in accordance with my invention; I Figure 2 is a vertical sectional view showing the mixing device in position in an intake manifold;

Figure 3 is a section on the line 33 of F ig ure 1;

Figure 4 is a section on the line 44 of F ig- 5:5 ure 1;

Figure 5 is a plan of the blank from which the'mixing device is formed.

Referring now more particularly to the drawing, the numeral 10 generally designates (it: a plate adapted to be inserted between adj acent sections of an intake manifold or between the junction between the intake manifold and the carbureter illustrated at I and C respectively and extend transversely of the bore of the intake manifold. The plate is provided with a plurality of nested substantially triangular openings 11, having the outer side edges 12 of arcuate contour, the circumference of the circular area defined by these arcuate edges being slightly less than the internal diameter of the manifold. The remaining or inner edges combine to define concentered ribs 13 attached at their outer ends to the marginal edge 14 and at their inner ends to one another. The arcuate edges of the openings are all swedged to one side of the plate, so that the portion of the plate defined by the wall of the manifold is in the form of a group of arcuate troughs having radial branches, which are joined at their centers. Each of these radial branches is provided with an opening 15, the purpose of whichwill presently appear.

The metal separated from the plate in the formation of one of the openings is left attached to one of the marginal edges and is forced ,to the same side of the plate as that toward which the edges of the openings are swedged until they assume angles of approximately 37 to the plate.

The free ends of the vanes 16 which are thus formed are preferably longitudinally split, as indicated at 17 and the branches thus produced slightly deflected with respect to one another, so that they are disposed at different angles. 7

The construction recited is particularly adapted for use at the lower intake end of a vertical branch of the intake manifold and when in applied position thereon, will act upon the partially vaporized mixture, passing through the openings of the plate to cause the same to rotate, so that heavier particles are deflect-ed against the wall of the manifold and are shattered so that theymay be more readily picked up by the air stream. By subdividing the ends of the vanes, the mixing effect is materially increased, in that the number of air streams produced is multiplied and air streams are produced which are traveling at different angles and accordingly have a tendency to cross and intercept one another with considerable force, so that a thorough mixing results. Any fluid which may cling to the wall of the intake manifold and pass downwardly therealong will collect in the troughabove described and will pass to the openings 15 of the concentered branches thereof, with the result that it is again introduced to the air stream at a point adjacent the center thereof and may be again acted upon by the whirls and eddies produced by the vanes.

It will be obvious that a construction of this character provides an apparatus which may be very readily installed, may be very cheaply manufactured and which will eiiiciently act to promote a proper mixture of the fuel with the air by which it is carried.

It will also be obvious that the construc-- tion hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed.

I claim 1. A mixing device adapted to be inserted between an intake manifold and carbureter, comprising a plate provided with a plurality of apertures disposed to form concentered portion-s therebetween, a plurality of vanes, one for each of the apertures, the vane of each aperture being connected to an edge of an adjacent one of said portions and disposed over the aperture at an angle to the plate and to its perpendicular axis, and raised flanges struck up about the remaining portions of the apertures designed to form arcuate troughs with the wall of the manifold, said flanges each continuing along the free edge of a concentered portion.

2. A mixing device adapted to be inserted between an intake manifold and a carburetor, comprising a plate provided with a plurality of apertures disposed to form concentered portions therebetween, a plurality of vanes, one for each of the apertures, the vane of each aperture being connected to an edge of an adjacent one of said portions and disposed over the aperture at an angle to the plate and .to its perpendicular axis, and raised flanges struck up about the remaining portions of the apertures designed to form arouate troughs with the wall of the manifold, said flanges each continuing along the free edge of a concentered portion, said vanes each having its free end split with one of the portions thus formed deflected with relation to the other.

3. A mixing device, comprising a plate adapted to be inserted between an intake manifold and a carbureter and having a plurality of segmental openings stamped therein leaving radially directed portions between the openings, the material forming a vane stamped from each opening being in tegrally connected to one of said portions vand disposed over the adjacent aperture at an angle to the plate, a raised flange formed about the edge of each of said openings, said flanges forming with the adjacent manifold Wall arcuate troughs and each further forming a trough of a radial portion with the adjacent vane of the portion, and each of said radial portions having a drain opening formed through the bottom thereof at a point adjacent the radial center of the plate.

4. A mixing device, comprising a plate adapted to be inserted between an intake manifold and a carbureter and having a plurality of segmental openings stamped therein leaving radially directed portions between the openings, the material forming a vane stamped from each opening being integrally connected to one of the said portions and disposed over the adjacent aperture at an angle to the plate, a raised flange formed about the edge of each of said openings, said flanges forming with the adjacent manifold wall arcuate troughs and each further forming a trough of a radial portion with the adjacent vane of the portion, and each of said radial portions having a drain opening formed through the bottom thereof at a point adjacent the radial center of the plate, each of said vanes having its free end split and one of the portions formed at OJPOSltG sides of the split deflected with relatlon to the other.

In testimony whereof I hereunto afiix my signature.
